Hello there,
Okay, well you have asked what quantities are equivalent to 250 meters well 250 meters would be...
- 25000 centimeters
- 0.25 kilometers
- 820.20 feet
Hope I helped,
Amna
the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the <u>radius will be 3</u>
slant height is
h is 4.7 and r is 3
<u>slant height is 5.58427</u>
lateral surface area
<u>lateral surface area is 52.63053</u>
total surface area
<u>total surface area is 80.90486</u>
I´d say "d" is the distance from the eye to the wall.
Now substracting 1.2-1 you´ll get the distance of the wall of the smallest triangle = 0.2 And you do 1.5-0.2= 0.3 that´s the distance of the wall of the other triangle. Then you solve everything with Pitagoras theorem. You have 2 rectangle triangles.
B+alfa=45°
tan^-1(0.2/d)=B
tan^-1(1.3/d)=alfa
THEN:
tan^-1(0.2/d)+tan^-1(1.3/d)=45°
Now you have 3 ecs and 3 variables.
alfa,B and "d"
Answer:I think it's trying to find the area of which is a 5 times 2 = 10
Step-by-step explanation:
The cofunction of cos is sin(90-x)
90 degrees is equal to PI/2
The cofunction becomes sin(PI/2 - 2PI/9)
Rewrite both fractions to have a common denominator:
PI/2 = 9PI/18
2PI/9 = 4PI/18
Now you have sin(9PI/18 - 4PI/18)
Simplify:
Sin(5PI/18)
